Writing automation clients for versions of Office including 2007

[Mark Booth]

I have code that binds to the PIA for Word 2000 that I need to keep running.
One of my clients wants to upgrade to 2007 and I would like to make the same
code work for both. All of the kb articles I have read imply this should be
OK as long as I use the earlier references, but they only discuss the
versions from 97 to 2003. When I try to use the code with 2007 I get
IEHExceptions.

Am I missing some documentation? or can anyone advise me whether what I want
to do is possible (and give me a clues as to how to do it!)

Thanks

IEHExceptions.
Auch, Interface implementation problems (the PIA's) ...

I'm afraid y'll have to wait for fully Office 2007 supported PIA's for this.

Thank you, Perry. When I opened VS it said it was updating my references, so
I had assumed, obviously wrongly, that it was fixing the PIAs. I don't
suppose anyone has any idea when they will be available, or why they should
be seen as an unncessary extra for delivery whenever? I seem to recollect
something about "developers, developers, developers"...

Sorry couldn't resist that.

Having thought for a few seconds longer, the PIA for 2007 might solve the
IEHExceptions, but I shouldn't be getting them if 2007 continued the
consistency with earlier versions.

The PIA won't let me use the same executable for multiple versions of Word,
I will need to recompile and keep separate codebases for 2007 and earlier.

I assume that the v-tables have been changed in 2007. I seem to have to do a
lot of assuming, in the apparent absence of any documentation.

KB 245115 talks about having to work around "compatibility problems between
multiple versions of a component that has improperly modified or adapted its
interface between versions" which sounds like what I have here.

mmm... "improperly"...
